СПОСОБ УДАЛЕНИЯ ПАРАФИНОВЫХ ОТЛОЖЕНИЙ В НАСОСНО-КОМПРЕССОРНЫХ ТРУБАХ НЕФТЯНЫХ СКВАЖИН

摘要

FIELD: oil industry. ^ SUBSTANCE: method includes washing tubing pipes using solvent - condensed light hydrocarbons, produced using centrifugal forces of hydraulic cyclone, with insertion of it through behind-pipe space into said tubing columns and circulation with down-pump operating in towards-self mode. Said solvent contains admixture in form of special surfactant, washing is performed at temperature close to temperature of melting of paraffin with loss of said solvent 5-10 m3 in one well. ^ EFFECT: higher efficiency, broader functional capabilities.
